multi-trait multi-method methodn
also MTMM method
a statistical procedure to test construct validityof a test by means of
examining a correlation of two or more traits (e.g. L2 listening ability and
L2 reading ability) using two or more methods (e.g. multiple-choice
itemand self-assessment). For example, a positive high correlation
between two different tests that are claimed to measure the same trait is
evidence of convergent validity, whereas a low correlation between two
tests that are claimed to measure different traits using the same method is
evidence of discriminant validity.
multivariate analysisn
a general term for various statistical techniques that are used to analyze
multivariate data, such as factor analysisand regression analysis.

multivariate datan
(in statistics) data that contain measurements based on more than one
variable^2. For example, if we were measuring a student’s language
proficiency and tests were given for reading, writing, and grammar, the
resulting information would be multivariate data because it is based on
three separate scores (three variables).
